Flex Seal is a rubberized sealant spray coating that sprays out as a liquid, seeps into cracks and holes, and dries to a watertight, flexible rubberized coating. It stops leaks fast and creates a durable, weather-resistant seal that remains flexible in extreme heat or cold. The coating adheres to a wide variety of surfaces and stays pliable while protecting against rust, corrosion, and water damage for years.
Whether you're repairing a leaky roof, sealing PVC pipes, weatherproofing windows, or fixing foundation cracks, Flex Seal provides an easy-to-apply solution using a portable aerosol spray can. Unlike traditional paint, this thick liquid fills gaps and holes completely, covering fast with just one pass. Once fully cured, the flexible coating can be painted any color to match your project.
Features and Benefits

- Fast Application: Sprays on easily from an aerosol can and covers quickly with minimal passes, making repairs faster than traditional paint.
- UV Resistant: Resists UV degradation to keep the coating intact and effective over time, even under direct sunlight.
- Multi-Surface Adhesion: Works on wood, metal, tile, concrete, fabric, glass, plastic, aluminum, rubber, and many other materials.
- Vibration Reduction: Deadens noise and reduces vibration on HVAC ducts, metal roofing, and other structures.
